PULSE SELECTOR Russian patent published in 2014 - IPC H03K5/26 

FIELD: electricity.

SUBSTANCE: invention can be used for logic processing of positive pulse signals x₁,…,x_n∈{0.1} synchronised against their leading edge and having pulse lengths of τ₁,…,τ_n. The operations min(τ₁,…,τ_n), supramin(τ₁,…,τ_n), submax(τ₁,…,τ_n), max(τ₁,…,τ_n) are described. The device contains n-1 of EXCLUSIVE OR (1₁,…,1_n-1) elements, n-1 of locking keys (2₁,…,2_n-1), a resistor (3), n-2 of unlocking keys (4₁,…,4_n-1) and n-2 of additional locking keys (5₁,…,5_n-2).

EFFECT: ensuring reproduction of any of the above operations.
